The Danger Zone in the Anterior Neck: Anatomical Landmarks to Avoid Injury to Anterior Jugular Vein During Face-Lift and Neck-Lift

Background: An estimated 125,711 face-lifts and 54,281 neck-lifts were performed in 2015. Regardless of the technique employed, facial and neck flap elevation carries with it anatomical risk of which any surgeon performing these procedures should be aware of. Statistics related to anterior jugular vein injury during these procedures have not been published. Objective: To define a "danger zone" that will contain both of the anterior jugular veins on the basis of anatomical landmarks to aid surgeons with planning their surgical approach during rhytidectomy in the anterior neck region. Methods: Ten fresh tissue heminecks were dissected. All specimens were dissected under loupe magnification in a 45° (face-lift) position in which a midline incision was used for exposure. Measurements from the anterior jugular vein to the hyoid, thyroid cartilage, and cricoid cartilage bilaterally were taken. The transverse distance between the anterior jugular veins at the level of the hyoid, thyroid cartilage, and cricoid cartilage was also measured. Results: The anterior jugular veins remain in an anatomical danger zone while they travel in the anterior neck. Regardless of anatomical variation of the vessels between bodies, they generally reside in this danger zone from their inferior emergence behind the sternocleidomastoid muscle until they branch in the suprahyoid region. Conclusions: Knowledge of the anatomy, course, and location of the anterior jugular veins through the anterior neck based on anatomical landmarks and distance ratios can facilitate a safer dissection during rhytidectomy procedures.
